Open source firewall

Nothing beats a standalone quality hardware firewall, except for one that happens to be open source and replicates most of what the big players do for the price of free. If one of one of our customers is looking to filter out traffic or particular websites, look no further than open source community firewall. This all-in-one Linux distro with powerful firewall functionality can be easily deployed onto an aging system that can likewise be turned into the primary firewall of a small business (or mid-size business, if you so wish.)

While this nifty system is quite powerful, it does require some re-architecture of a company’s network, so you will need to plan your downtime and installation path appropriately. A great overview of the layout of a protected network can be found on our installation guide routine. One of the other requirements you will need to be mindful of is that each “logical network” you want to configure within will require an additional network card with patch cord tying back into the physical infrastructure. This may be a challenge for PCs that may have only 1-2 PCI slots that are full. A system best suited for running will likely be a mid-tower to full-tower ATX system due to the hardware requirements.
